OlL-STRAINER AND JOURNAL-PRESERVER.

SPECIFICATION forming part of Letters Patent No; 769,966, dated September 13, 1904.

' Application filo May 26, 1903- Serial No. 158,794:- (No model.)

To all whom it may concern:

Be it known that I, ALBERT R. WARNER, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Oil-Strainers and Journal-Preservers, of which the following is a specification.

My invention relates to a new and useful improvement in oil-strainers and journal-preservers,and has forits object to provide a small tubular attachment which may be inserted in all lubricating devices which supply oil to journals or pistons, this attachment straining and purifying the oil before it comes into the journal-box or piston-cylinder.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in Which Figure 1 is a longitudinal vertical section through the upper portion of a locomotivejournahshowing my attachment applied thereto; Fig. 2, a cross-section through the upper portion of a locomotive journal-box; Fig. 3, a plan view of a locomotivejournal-box, showing a portion of the top plate broken away; Fig. A, a perspective View of the strainer attachment designed to be placed in locomotivejournals; Fig. 5, a vertical section through an oil-feed cup with my strainer attachment applied thereto; Fig. 6, a perspective view of the strainer attachment adapted for the oil-feed cup; Fig. 7, an elevation of the lower portion of an up-drop sight-feed lubricator, showing my strainer attachment located in the feed-pipe; Fig. 8, a perspective view of the strainer attachment shown in Fig. 7.

Referring to Figs. 1, 2, 3, and 4, A represents a locomotive journal-box which is of the usual construction, having a cavity B sunk in the top of the same. Over the top of the cavity is arranged the usual plate C, and descending from the cavity B to the journal are the vertical holes D, and as in the usual con.

struction the cavity B is filled with waste or other absorbent material, and this waste is soaked with oil, the oil passing down through the holes D to the journal. It is a well known fact that the oil will carry down with it considerable grit, and therefore in time injure the journal. My improvement consists in inserting strainers between the waste and the holes D, so that the oil will be purified when it reaches the journal. These strainers are tubular in form, as shown in Fig. 4E, and each consists of the solid metal frame E, this frame comprising an upper ring E and a lower ring E and vertical connecting bars E joining these two rings together. The frame E is composed of two tubular frames similar in form and adapted to be inserted one in the other, a tube of fine wire-gauze F being interposed between the two tubular frames, and thus the walls of the attachment consist of the gauze. The upper portion of the holes D are bored out slightly larger, so as to form a shoulder, the attachments fitting into these enlarged portions of the holes, so that the upper edge of thering E is flush with the bottom of the cavity B and the upper ring E is flush with the top of the plate (J. Thus it will be seen that the waste will surround the strainer attachments, and the oil from the waste must necessarily pass through the gauze and be strained before entering the holes D. The plate 0 is of course provided with openings through which the upper ring E of the strainers may pass, and above these openings are provided the swinging covers G, the center of each cover being provided with wiregauze G, which will allow the air to enter for the proper feed of the oil, but prevent dust from entering the holes D. H is an opening in the center of the journal-box for supplying oil to the waste, and this opening is also adapted to be covered by a cover G.

In lubricating locomotive-journals it is customary at times to place tallow in with the Waste; but it is necessary that the tallow be melted before it can flow to the journal, and thus the journal must be hot enough to heat the oil-box before the tallow may reach the journal and cool it. In my device I intend to prepare tallow in sticks small enough in diameter to be inserted from above downward through the straining attachment into the holes D, so that the sticks will rest upon the journal, as shown in Fig. 2, I representing the stick of tallow. In this manner as soon as the journal-box is the least bit heated sufficient tallow will be melted from the stick to cool the journal, and the oil is free to flow down the tube around the tallow to the journal at all times. It is also customary at times to mix graphite with the waste in the locomotive journal-box and depend upon the oil carrying down some of the graphite with it; but in my construction the holes D are open clear through to the top of the journal-box on account of the strainer being attached in the upper end of the holes, and thus when it is necessary to add graphite the same can be placed in the holes through the strainers, and therefore come in contact with the journal.

In Fig. 5 I have shown my strainer attachment as applied to an ordinary oil-feed cup. This strainer attachment, as shown in Fig. 6, also consists of two tubular frames J, fitted one inside the other with a tube of wire-gauze K in between them. The inner tubular frame extends upward above the outer tubular frame, so as to form the tubular extension J. The strainer attachment is adapted to fit around the tube in the center which contains the hole L, through which the oil passes from the cup to the feed-tube. Thus the oil must pass from the cup through the gauze K of the strainer attachment before it reaches the hole L, and the oil will thus be purified when it enters the feed. In order to always keep the strainer attachment tight, I provide the cap M, which fits over the extension J of the strainer, and a spring N is interposed between the upper edge of the extension J and the top of the cap M, thus always holding the strainer attachment in close contact with the bottom of the oil-cup.

In Fig. 7 I have shown my strainer attachment as applied to an ordinary up-drop sightfeed lubricator. 0 represents the lower feedarm of the lubricator, which will necessarily be horizontally lengthened somewhat to provide room for my attachment, and this feedarm 0 is provided in its horizontal tubular portion with a vertical bore in which the strainer attachment may fit, caps P closing the opening at each end and holding the attachment in place. The strainer attachment in this case consists of a tubular frame Q, which only has wire-gauze R upon one side, the other side of the frame next to the oilreservoir being provided with an opening S. Thus the oil will pass through the opening S, then through the gauze to the feed-tube. I provide in the feed-arm O between the strainer attachment and the oil-reservoir a valve T, whereby the oil may be cut ofi, the caps P removed, and the strainer cleaned or a new one inserted at any time.

It will thus be seen by the foregoing description that by means of a very simple attachment which can be applied to all forms of lubricating devices the oil may be strained and purified as it is used, and thus preserve the journal.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. An oil-strainer consisting of a tube of wire-gauze, a framework surrounding-the outside of the tube of gauze, and a framework fitted inside of the tube of gauze, each of said frames being provided with openings formed through the walls thereof which openings register with one another, as and for the purpose specified.

2. An oil-strainer consisting of a tube of wire-gauze, metallic rings surrounding the tube at the top and bottom, metallic rings fitted inside of the tube so that the wire-gauze will be confined between the outside and inside rings, and bars connecting the top and bottom rings both inside and outside of the tube, as and for the purpose specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

ALBERT R. WARNER.
